Venox 250 / Re: Venox vacuum and coolant air bleed hose routing
« on: October 02, 2015, 12:31:03 PM »
Awesome, I had everything routed properly, but that was definitely the answer I was looking for. Thank you for taking the time to line that out.

I have the carbs off the bike right now, already did a full carb clean and they are ready to go back on, one thing I have been looking for is a new air cleaner for this bike. I know the one in there is at least 5 years old, maybe older. But all my normal sources for getting something as simple as an air filter don't carry that one. I did find it over place online but they wanted 26 bucks just to ship it, that was more then they wanted for the filter but still makes a20 buck filter 40 week almost 50 really. Any suggestions on this?

Venox 250 / Re: Carb Cleaning

I noticed that this forum is pretty much dead, I'm no kymco mechanic however I am a Harley tech by trade, I have pulled the carbs off of the ol lady's venox and I do know what screws you are talking about. The best place to go to replace them is going to be a place like fasten all. I have a place by me called Conroe Bolt and fastener, I use stainless steel to replace most hardware as I hate rust.

On another note if you are planning to jump your bike with a car don't turn the car on. The amps that a car alternator puts out can fry the charging system on a motor cycle. Just leave the car off and hook up the battery alone should be plenty to jump your bike. Good luck.

Venox 250 / Transmission vent
« on: September 19, 2015, 12:20:03 AM »
At idle I have no issues with it, however when I start to get higher rpm (only in gear) I get oil coming out of the transmission vent, very little white smoke, only a wisp here and there is any at all, but it's pushing oil all the way up into the breathe at speed. What could be causing this? At first I thought it had to much oil in it, but according to the window it's dead on right, and the oil level hasn't dropped, however the bike has no acceleration, won't hold idle unless I turn it up, and in higher rev it starts to miss and have no power, any suggestions? Trying to straighten this little bike out for the ol lady and is rather work on the Harleys any day, this thing is finikye. I just replaced the motor, it's an 04 and the motor came from an 05, had really good compression, in neutral it will rev nicely and sounds strong (other then the fact it won't hold idle), riding is another story

if you still need i can send pictures of all the vacuum lines on my bike, im thinking i may have to remove the carbs as well so i photographed everything to know exactly where everything goes back.  Let me know.


I'm in the same boat, trying to figure out all the vacuum lines and where the two coolant air bleed lines go, seems to me they attach to the carbs but to me that doesn't seem right, I just installed a new motor in the bike and need to hammer out thease last few issues. If you can send the pics to me as well it would really help, thanks

It does have diagrams on the first page of each section, however it doesn't show what lines go where. I'm a Harley tech by trade, however never have I had to assemble any vacuum system that has been so complex, there is a small digram under the seat of the bike but it seems to be incomplete as there are more lines and connections then shown. Hopefully someone will be able to answer this question. The bike will start and run however it won't hold idle on its own and before I start to adjust the carbs I want to make sure the lines are right, also the two air bleed lines coming off the thermostat housing I want to make sure are right before I fill the system with coolant. So I can't run the bike to do any adjusting until thease lines are proper. Or the way I currently have then is confirmed. Thank you any way,

The bike has been a great bike over the years which is the reason I decided to fix it instead of scraping it. Just got to get the lines right then adjust it to run properly and I think she has many more years left in her.

Venox 250 / Venox vacuum and coolant air bleed hose routing
« on: September 16, 2015, 09:32:31 PM »
Just replaced the motor in my girls 2004 venox. The original motor had spun a rod bearing and destroyed the crank. The bike is back togather however the Manuel doesn't cover the routing of the vacuum lines or the air bleed hoses for the coolant system, and finding the answers has been hard. Here is where i sit.

I have the two lines coming off of the intakes one front and I've rear, the rear has a t fitting and the little line runs to the petcock. The other line coming off of the t I'm guessing runs to the first canister under the side cover? There is also a canister down by the exhaust. It has a line coming off and up by the first canister, it ends in a Y fitting that I'm guessing then runs to the first canister and also the front intake? Is this correct?

Next are the air bleeds for the coolant system. Both are connected at the thermostat housing, however I don't know where they run, but the best I can tell it's too two v shaped fittings located on the carbs that have a hose connecting them togather, is this correct? The Manuel does not cover the routing of thease hoses and in trying to finish this bike up for her. Thank you for any help.
